My math teacher said I'd need this stuff

The day has finally come when math works for us:

A mathematician has explained how to stabilise a wobbly table without needing to jam a beer coaster under one of the legs.

Australian researcher Dr Burkhard Polster, of Monash University in Melbourne, and his international colleagues have calculated that turning a rectangular table around on most surfaces will cure the wobble.

The table will not necessarily be horizontal, which means your beer may still slide off, but it will not wobble.
